Flexible VCD having domed center and flat central bottom ring

ABSTRACT

A Flexible VCD Having Domed Center and Flat Central Bottom Ring and Method of Making Thereof is disclosed. The disc will has a flat data storage section of its substrate that is less than 0.7 millimeters thick, while the central region of the disc is defined by a dome structure adjacent to the spindle aperture that is of standard digital disc thickness. The disc is thin enough such that its substrate is flexible. The dome structure is shaped to provide the widest compatibility with player/recorders, as well as with disc printing systems. Disc versions are available that provide conical dome structures, as well as slivered dome structures of both conical and rectangular cross-section, and a combined design having a plurality of raised protrusions on the top surface of the disc, and a flat central ring protruding from the bottom surface of the disc. The method for manufacturing the discs simply requires the replacement of the conventional stamper holder with a stamper holding having a non-flat face.
